Minecraft Launcher crashing, when I trying to start Minecraft.

Had to start Minecraft 1.8.9 Forge,
but new launcher just flew
1. I started Minecraft Launcher
2. Pressed "PLAY" button into that
3. And it's flew.
I have a video about that: https://youtu.be/CnUNln-H3Ek.
...and launcher crashing on vanilla too: https://youtu.be/KD5k_kURgBI
